It is believed to be one of the of the largest seizures globally and tops the £114m confiscation made by the Met in June.

A 39-year-old woman, arrested on 24 June on suspicion of money laundering offences, has been interviewed over the most recent seizure.

She has been released on bail.

Deputy Assistant Commissioner Graham McNulty said: “Proceeds of crime are laundered in many different ways. While cash still remains king in the criminal world, as digital platforms develop we’re increasingly seeing organised criminals using cryptocurrency to launder their dirty money.

“Whilst some years ago this was fairly unchartered territory, we now have highly trained officers and specialist units working hard in this space to remain one step ahead of those using it for illicit gain.”

The investigation continues.
